As long as the already-installed components are where they should be, I would think your brackets should line up where the mounting bolts go ??
If your setup is close to my 5.7, the tensioner pully bracket straddles on the A/C compressor & an arm-brace to intake-thermostat bolt then a bracket accepts to bolts at alt-bracket / 3 bolts & below/behind A/C compressor.

Boy,.... like 7 points to secure tensioner.... on a 5.7

I pulled a drawing from my '88 GMC service manual, showing a 7.4.

Maybe this might help? ( I have no clue what that cylinder is, next to alternator)
